Abstract Electrophysiological signals across species and recording scales exhibit both periodic aperiodic features. Periodic oscillations have been widely studied linked to numerous physiological, cognitive, behavioral, disease states, while the “background” 1/f component of neural power spectra has received far less attention. Most analyses are conducted on a priori , canonically-defined frequency bands without consideration underlying structure, or verification that signal even exists in...
In this paper, we present an analysis of 59,000 OkCupid user profiles that examines online self-presentation by combining natural language processing (NLP) with machine learning. We analyze word usage patterns self-reported sex and drug status. doing so, review standard NLP techniques, cover several ways to represent text data, explain topic modeling. find individuals in particular demographic groups self-present consistent ways. Our results also suggest users may unintentionally reveal...
